JOHN AULD, OF CHICAGO, ILLINOIS.

ERASER-HOLDER.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Appflcation filed May 17, 1918. Serial No. 235,102.

T all whom it may concern:

Be it known that I, JOHN AULD, a citizen of the United States, and aresident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Eraser-Holders, of whichthe following is a specification.

My invention relates to an improved eraser holder and is particularlyadaptable for holding long rectangular erasers.

The object of the invention is to provide a simple and practical holderinto which the eraser can readily be slipped and frictionally heldduring use of the combination, the construction being such that theeraser may be swung into various positions on the holder and the holderbeing provided with a' brush for cleaning a surface after erasurethereon.

My improved device is clearly illustrated on the accompanying drawing inwhich- Figure 1 is a plan view,

Fig. 2 is a side view,

Fig. 3 is a sectional View on plane 33, Fig. 2, and

Fig. 4 is an end view.

The holder is a U-frame 5 bent from a length of fiat metal barpreferably of springy material. The outer ends of the bar have openings6 and 7 for the insertion of tubular rivets 8 and 9 which pivotallysupport the U-shaped jaw members 10 and 11 at the U-frame ends. Thesejaw members are bent up of sheet metal blanks of any desired shape andthe width of the jaw members between their wings a and b is such as tomore or less frictionally receive between them the sides of erasers,such as E.

When the U-frame 5 is formed its sides are preferably bent toward eachother beyond parallelism so that when an eraser is inserted in the jawmembers the U-frame sides must be spread apart and will then exertclamping action on the eraser to hold it firmly in position. The innerprojecting ends of the rivets will be pressed into the eraser materialand will assist in holding it securely in position during use of thestructure. When the eraser is inserted it can be readily swung with thejaw members on their pivots into any angular position relative to theU-frame, for under different conditions different angles are moredesirable for accomplishing the best erasing results, the holder servingas a grip.

I preferably provide a brush on the holder for cleaning an erasedsurface. The brush structure shown comprises a sheet metal cup 12 andthe bristles 13 held therein by wire 14. Bristles are first assembled inparallel arrangement and then a bunch bent intermediate its ends and alength of wire inserted through the bend. The wire ends 0 and d are thendrawn through holes 15 and 16 in the base of the cup 12, and the bend ofthe bristle bunch will be securely seated in the cup. The wire ends arethen inserted through the holes 17 and 18 in the yoke of the frame 5 andtheir inner ends soldered, burred, or otherwise secured with referenceto the frame whereby the cup 12 is securely fixed to the frame.

I thus provide a simple, neat and practical holder for erasers whichwill permit erasers to be used with greater precision and to betteradvantage. As the eraser becomes worn away the holder will still permitaccurate use of the remaining eraser end and there will consequently beless wastage.

I do not of course desire to be limited to the exact construction andarrangement shown as changes and modifications can no doubt be madewhich would still come with in the scope of the invention.

I claim as follows:

1. An eraser holder comprisin a U-frame, jaw members pivotally supportedat the ends of said frame for receiving an eraser.

2. An eraser holder comprising a U-frame of spring metal, U-jaws pivotedat their bases to the ends of said U-frames with their sides opposed toeach other to receive an eraser between them.

3. An eraser holder comprising a U-frame of spring metal, U-shaped jaws,pivot members extending through the ends of said U- frame and the basesof said jaws to pivot said jaws, the sides of said jaws extendinghorizontally toward each other to receive an eraser.

4:- An eraser holder comprising a U-frame of spring material, U-jaws atthe ends of said U-frame for receiving and holding an eraser.

In witness whereof, I hereunto subscribe my name this 14th day of May,A. D. 1918.

J OHN AULD.
